What is the significance of the sustentaculum tali?
The sustentaculum tali is one of the most important anatomic marks in the calcaneus. As it was constrained by the joint capsule and surrounding ligaments and tendons, the sustentaculum tali fragment will seldom be displaced from the medial wall of the calcaneus, even if the severe calcaneal fracture occurs.
What is the sustentaculum tali and where can it be found?
ANATOMY. The sustentaculum tali is a triangular projection found on the medial surface of the calcaneus, with its base facing posteriorly and apex (Fig 3a) anteriorly. The superior surface contains the middle calcaneal facet.
What passes under sustentaculum tali?
plantar calcaneonavicular ligament (anterior surface) deltoid ligament (medial surface) medial talocalcaneal ligament.
Does the sustentaculum tali support the talus?
The malformed sustentaculum tali is unable to support the head of the talus, and superimposed body weight allows the talus to adduct and plantar flex while the calcaneus simultaneously everts.
What does Sustentaculum mean?
Medical Definition of sustentaculum : a body part that supports or suspends another organ or part.
Is sustentaculum tali medial or lateral?
The sustentaculum tali is on the plantaromedial aspect of the calcaneus. Injuries involving the medial aspect of the hock often involve the sustentaculum tali and adjacent tarsal sheath.
Is the sustentaculum tali medial or lateral?
What is the sustentaculum tali horse?
The sustentaculum tali is on the plantaromedial aspect of the calcaneus. Injuries involving the medial aspect of the hock often involve the sustentaculum tali and adjacent tarsal sheath. Injury usually occurs from direct trauma, most commonly from a kick wound. Lameness is often severe.
Where is Sustentaculum?
The sustentaculum tali is on the plantaromedial aspect of the calcaneus.
What is the meaning of sustentaculum tali?
Medical Definition of sustentaculum tali. : a medial process of the calcaneus supporting part of the talus.
What causes the sustentaculum tali to become infected?
The sustentaculum tali is prone to trauma over its plantaromedial aspect, resulting in bone proliferation within or adjacent to the insertion of the retinaculum on the calcaneus. Some wounds also cause contamination or infection of the tarsal sheath.
What causes fracture of the sustentaculum tali?
Fractures of the sustentaculum tali occur rarely. These injuries are caused by acute trauma, mainly in the form of kicking injuries. The skin can be perforated, resulting in communication with the tarsal sheath of the deep digital flexor tendon.
Is the placement of sustentaculum tali necessary for Type II calcaneal fracture fixation?
Conclusions: The placement of sustentaculum tali screw is essential for fixation of type II calcaneal fracture to achieve the biomechanical stability. KEY WORDS: Calcaneal fracture; Sustentaculum tali; Screws; Finite element analysis; Biomechanics.
